How to enable debugging?

[majunze2001]

Can I build the driver with debug symbols? I tried to gdb on the kernel, but it seemed the module did not export any symbols.

how do you use gdb to debug this driver? can you please give me some blog or doc to learn?

You can debug it the same way you debug any Linux kernel driver for which you have the source code. Note that you cannot debug the GSP-RM firmware itself, because Nvidia does not provide the tools for that.

NV_BUILD_TYPE=debug make modules -j$(nproc)

Try:

make modules -j$(nproc) DEBUG=1 NV_VERBOSE=1 CONFIG_DEBUG_INFO=y
